LLS2G561MELB

The LLS2G561MELB from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LLS series, rated 400 V and 560 µF with polarized terminals. It is an 85°C-standard device designed for general-purpose applications that require high-voltage, high-capacitance bulk components.

Key reliability features include a rated lifetime of 3000 hours under rated ripple current at 85°C and RoHS compliance (2011/65/EU, (EU)2015/863), making it suitable where sustained ripple endurance and regulatory compliance are needed.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance at a 400 V rated voltage, with a capacitance tolerance of ±20% (120 Hz, 20°C).
• Snap‑In Radial Can Package — Snap-in terminal type in a radial can for robust board-mounted power applications.
• Rated Endurance — Endurance: meets specifications after 3000 hours of DC bias plus rated ripple current at 85°C; capacitance change within ±20% after test.
• Ripple Current Capability — Specified ripple current ratings of 2.85 A at 120 Hz and 4.075 A at 50 kHz to support continuous ripple handling in powered circuits.
• Operating Temperature — Suitable for operation from −25°C to +85°C for the 350–450 V voltage range.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) maximum for 400 V is 0.20; leakage current specification follows I ≤ 3√(C·V) µA after 5 minutes at 20°C (C in µF, V in V).
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Power Systems — Intended for general-purpose use in circuits that require high-voltage, high-capacitance bulk components.
• Ripple-Intensive Circuits — Rated ripple current and 3000-hour endurance at 85°C make this part suitable where sustained ripple handling is required.
• Bulk Energy Storage — Polarized, high-capacitance design for applications needing energy buffering or smoothing within its rated temperature and voltage limits.

Unique Advantages

• High Voltage and Capacitance Combination — 400 V rating paired with 560 µF provides bulk capacitance where higher DC voltage is present.
• Proven Endurance — Withstands 3000 hours of rated ripple current at 85°C, supporting long-term reliability under sustained thermal and electrical stress.
• Frequency-Qualified Ripple Ratings — Explicit ripple current specifications at 120 Hz and 50 kHz allow designers to size and qualify parts for both low- and higher-frequency ripple conditions.
• Measured Loss and Leakage Limits — Defined tan δ and leakage current limits (I ≤ 3√CV after 5 minutes at 20°C) enable predictable thermal and leakage behavior in designs.
• Temperature Performance for High-Voltage Range — Rated for operation from −25°C to +85°C for 350–450 V parts, with an impedance ratio limit (Z(−25°C)/Z(+20°C)) of up to 8 for the 350–450 V range.
• RoHS Compliance — Meets current RoHS requirements for environmentally regulated designs.
